Assistance required: indoor quadcopter

the sensor works fine both through the benewake GUI and mission planner.
im getting readings all the way to 8m. funny thing is the bad lidar health message is perpetually there even when i have live readings from the sonarrange status. Feels to me like theres some conflict going on between the sensors.

here are afew tests that i did today.
